Most people appreciate that a mattress protector is an essential, not an option, but what is the best waterproof mattress protector currently available?
To answer this we have to consider the features that combined together will lead us to the best waterproof mattress protector.
Well yes of course the best waterproof mattress protector is going to be waterproof but you have to think about what it is that makes it waterproof and how that affects its performance and comfort. A bin liner is waterproof but you wouldn't want to sleep on one.
Some mattress protectors use PVC or vinyl to make it waterproof but these are not particularly comfortable to sleep on. The problem is that they make you hot and sweaty and can be noisy to sleep on. If the mattress protector that you are thinking about buying doesn't tell you what it is that makes it waterproof then you have to assume that its not going to be comfortable.You would be better of choosing a different one.
The best waterproof mattress protectors use polyurethane to make them waterproof. Polyurethane is soft to the touch and quiet in use. Polyurethane is also breathable which means that it doesn’t make you hot and sweaty. People sometimes ask how something can be breathable and waterproof at the same time. The answer is that it is like our own skin, liquids cannot pass through but molecules can. So always make sure that any mattress protector that you buy uses polyurethane.
However some polyurethane protectors are better than others. This is because polyurethane can be applied in two different ways. In some production lines the polyurethane is applied to the fabric in a liquid form. This is then spread out using paddles, it then dries and sets. The problem with this method is that it allows low spots and high spots to form. High spots where the liquid has been quite deep and low spots where it was spread too thinly. These low spots wear more quickly and soon you get unprotected spots and patches.
The better method involves the polyurethane being manufactured separately as a thin uniform film which is bonded to the underside of the protector with no difference in thickness anywhere, this makes the protector last longer. The problem is that most manufacturers don’t tell you which method they use.
Absorbency is a very important issue when choosing the best waterproof mattress protector. The waterproof membrane on the underside means that any perspiration or moisture remains on the side that you are sleeping on. The more absorbent the upper surface is the more that perspiration spreads out and the wider it spreads the quicker it evaporates.
Cotton is very absorbent but polyester isn’t so the higher the cotton content the more absorbent it will be. Flat woven surfaces are generally less absorbent than terry towelling so the best waterproof mattress protector will have a cotton rich terry towelling upper surface.
A good waterproof mattress protector has to be able to deal with all sorts of liquids. This might be anything from a spilt cup of tea to a baby’s nappy leaking and countless other bodily fluid issues. You still have to be able to wash it to get it hygienically clean. If a protector can only be washed at 30c or 40c that isn’t high enough to do this thoroughly enough. 60c is the minimum wash temperature to clean it properly for a heavily soiled protector washing it at 90c is preferable. So, check the washing temperature before you buy
Dust Mite Proof
Dust mites live in all of our homes regardless of cleanliness. Dust mites require food to survive. They live off the tiny particles of skin that we shed and a mattress provides the ideal climate and food source. Dust mites reproduce very quickly and within a matter of months hundreds of thousands can infest one mattress. Not only is this an unpleasant thought but for some people who are allergic to the dust mites waste products this can lead to uncomfortable wheezy restless nights. If you can stop the supply of skin particles and moisture from passing through to the mattress then you won’t have a dust mite problem. A polyurethane waterproof membrane does just that.
So the best waterproof mattress protector needs to have a waterproof polyurethane membrane that has been applied to the underside as a separate bonded film, for comfort and performance, it needs to have a cotton rich terry towelling upper surface for maximum absorbency and it needs to be washable at up to 90c.
